Chapter 1 Introduction
This Wireless LAN Card is an IEEE 802.11g wireless LAN adapter. 802.11g is the latest in the
series of 802.11 specifications for wireless local area networks (WLANs) and provides data
transfer of up to 54 Mbps. Since 802.11g draft operates on the same frequency of 2.4 GHz as
802.11b, so it is backwards compatible with existing Wi-Fi devices!
It allows your computer to connect to a wireless network and to share resources, such as files
or printers without being bound to the network wires. Operating in 2.4GHz Direct Sequence
Spread Spectrum (DSSS) radio transmission, the Wireless LAN Card transfers data at speeds
up to 54Mbps. Both Ad-Hoc and Infrastructure mode are supported. For network security
concern, 64/128-bits Wired Equivalent Protection (WEP) algorithm is used. In addition, its
standard compliance ensures that it can communicate with any 802.11b/g networks.

54Mbps Wireless LAN Card User's Manual
Wireless LAN Basics
This section contains some Wireless LAN basics to help you better understand how the
product work together to create a wireless network.
Local Area Network (LAN)
Simply put, a LAN is a network that exists in a relatively limited area. A network is two or
more computers connected together sharing files and peripheral devices such as printers.
The Wireless LAN Card allows you to interact with other computers without having to run
cables normally associated with networks. This lets you move your computer around while
staying connected t o your network.
There are two ways to use the Wireless LAN Card. One way is to connect directly to one or
more Wireless LAN Card equippe d computers, for ming an Ad-Hoc wireless network. The
second way is to connect to an Access Point that gives you access to an existing wired LAN,
forming an Infrastructure wireless network.
2
Page 11
Chapter 1 Introduction
Ad-Hoc Mode
The Ad-Hoc Group offers peer-to-peer connections between workstations, allowing
communication between computers within range that have a Wireless LAN Card installed. A
wireless Ad-Hoc network can also access a wired LAN’s TCP/IP service (such as e-mail and
the Internet) by using a TCP/IP software router on an Ethernet equipped PowerBook or
notebook.
Note: Using the 802.11g card in Ad-Hoc mode, your target peer can be 802.11b or 802.11g
compatible wireless station. But you cannot connect to an 802.11a wireless station since
802.11a devices are not compatible with 802.11b/g devices.
Figure 1-1 Ad-Hoc Mode
3
Page 12
54Mbps Wireless LAN Card User's Manual
Infrastructure Mode
The Infrastructure network uses an AP or several APs as a gateway, linking the wireless
network to a wired LAN. As a result, portable workstations or desktops on your wireless
network have access to all of the features of your wired LAN including e-mail, Internet access,
network printers and file server.
Note: Using 802.11g card, you can connect to 802.11b or 802.11g compatible Access Point.
But you cannot connect to an 802.11a Access Point since 802.11a devices are not compatible
with 802.11b/g devices.
Figure 1-2 Infrastructure Mode

Chapter 1 Introduction
Roaming
Multiple Access Points can be installed to extend the wireless service coverage area for
seamless wireless access. Within an extended service area, all Access Points and wireless
clients must have the same Service Set Identity (SSID). Roaming among different Access
Points is controlled automatically to maintain the wireless connectivity at all times.

Chapter 2 Installing the Wireless LAN Card
This chapter describes the installation process of the driver and software for the Wireless LAN
Card. Proper driver installation is to allow the device to operate on your host computer while
the utility software, Wireless LAN Utility, is to help you configure and monitor your Wireless
LAN Card.
If you are using an embedded wireless solution, such as the Mini PCI wireless adapter, your
notebook is probably shipped with its driver and software properly installed. If this is the case,
just ignore this chapter and proceed with the configuration steps in next chapter.
In case you need to install the driver and software for any reason, follow the instructions
described in this chapter.

If you just want to access certain wireless network type, click the Advanced button on the
Wireless Networks tab to open the Advanced window. You can choose to connect to the
following networks:
The default network type is Any available network (access point preferred). In this network
type, your device will connect to any Access Points or Wireless LAN Cards available in the
air but Access Point always demands higher connection attempt priority.

Authentication
This tab allows you to configure the authentication settings of your Wireless LAN Card. The
most important setting for the Wireless LAN Card is to disable Enable network access
control using IEEE802.1X to ensure successful connection between the Wireless LAN Cards
and Access Points or other Wireless LAN Cards. You must disable this function for any
reason. Otherwise, there may be some problems happening during connection. For other
settings, we recommend you keep the default settings to minimize the proble ms during
connection.

Glossary
802.11 802.11 refers to a family of specifications developed by the IEEE for wireless LAN
technology. 802.11 specifies an over-the-air interface between a wireless client and a
base station or between two wireless clients.
Access Point An internetworking device that seamlessly connects wired and wireless networks.
Access Points combined with a distributed system support the creation of multiple radio
cells that enable roaming throughout a facility.
Ad-Hoc
(Peer-to-Peer)
An 802.11 networking framework in which devices or stations communicate directly
with each other, without the use of an Access Point (AP). Ad-hoc mode is useful for
establishing a network where wireless infrastructure does not exist or where wired
network services are not required. Ad-hoc mode is also referred to as peer-to-peer mode
or an Independent Basic Service Set (IBSS).
Bit A bit (short for binary digit) is the smallest unit of data in a computer. A bit has a single
binary, either 0 or 1.

Founded in 1884 as the AIEE, the IEEE was formed in 1963 when AIEE merged with
IRE. IEEE is an organization composed of engineers, scientists, and students. The IEEE
is best known for developing standards for the computer and electronics industry.
72
Infrastructure An 802.11 networking framework in which devices communicate with each other by
first going through an Access Point (AP). In I nfrastructure mode, wireless devices can
communicate with each other or can communicate with a wired network.
Page 76
IP Internet Protocol. The standard protocol within TCP/IP that defines the basic unit of
information passed across an Internet connection by breaking down data messages into
packets, routing and transporting the packets over network connections, then
reassembling the packets at their destination. IP corresponds to the network layer in the
ISO/OSI model.
IP Address An IP Address is a 32-bit number that identifies each sender or receiver of information
sent across the Internet. An IP address has two parts: the identifier of a particular
network on the Internet and an identifier of the particular device (which can be a server
or a workstation) within that network.
LAN Local Area Network. A communication network that serves users within a defined
geographical area. The benefits include the sharing of Internet access, files, and
equipment, such as printers and storage devices. Special network cabling (such as
10BaseT) is often used to connect the PCs together.
MAC Address The MAC (Media Access Control) Address is a 12 digit Hexadecimal number that
uniquely identify your network adapter on the network.
Media The materials used to connect network devices, such as twisted-pair wire, coaxial cables,
or fiber optic cables. Some networks do not use physical connecting media;
communications are achieved via radio waves instead.
Mbps Stands for millions of bits per second or megabits per second and is a measurement for
data transmission

WEP Wired Equivalent Privacy, a security protocol for wireless local area networks defined in
the 802.11b standard. WEP is designed to provide the same level of security as that of a
wired LAN. LANs are more secure than WLANs because LANs are somewhat
physically protected by their structure, having some or all part of the network inside a
building protected from unauthorized access. WLANs, which are over radio waves, do
not have the same physical structure and therefore are more vulnerable to tampering.
WEP aims to provide security by encrypting data over radio waves so that it is protected
as it is transmitted from one end point to another.
WLAN Wireless Local Area Network. A group of computers and devices that communicates
with each other wirelessly.
